Key Approaches Flashcards
What are the 6 approaches in biology
Behaviourism
Social learning theory
Cognitive approach
Biological approach
Psychodynamic approach
Humanistic approach
What is a paradigm
A set of rules or assumptions used by all members of a science community
What is an empirical method
Investigate concepts you can directly perceive
What is objectivity
Study in a way that is not biased
What is replicability
Studies should be designed in a way that you can repeat them in exactly the same way.
What are general laws
The idea behind the research should be to create an average law which works every time
Behaviourism : Ideas/beliefs
the idea that all behaviours are learned through interaction with the environment
Behaviourism : Research methods
Ivan Pavlov, John Watson, and B.F. Skinner used classical and operational conditioning.
What is classical conditioning?
A learning process that occurs when two stimuli are repeatedly paired: a response which is at first elicited by the second stimulus is eventually elicited by the first stimulus alone
Pavlov’s dog (1897)
Dogs would associate the sound of a bell (NS then CS) with the food (UCS), and drool (R) to the CS
What is operational conditioning?
A learning process where behaviours are modified through the association of stimuli with reinforcement or punishment
Skinner’s rat (1938)
Rats learnt from trial and error that pulling on a lever would release a food pellet. The lever pulling behaviour became more frequent and deliberate over time. The rats also learnt to press the lever to stop the floor of the cage being electrocuted for 30 seconds
What is negative and positive reinforcement?
Positive = adding a stimulus to increase a behaviour
Negative = removing a stimulus to increase a behaviour
Strengths of behaviourism
Little albert (Watson 1920) showed fear could be a learnt response, suggesting not instinctual, leading to development of behavioural explanation and counter conditioning treatments for phobias.
Behaviourists use objective scientific experimental methods - systematically manipulating variables (observable cause and effect)
Weaknesses of behaviourism
-Token economies seen as unethical
-Research mostly with animals therefore generalisation to human behaviour could be limited
- Environmentally deterministic, suggesting behaviours result from learning from the environment not free will.
Social learning theory : Ideas/beliefs
Social learning theory suggests that people learn through observation and imitation of role models, via vicarious reinforcement with the help of mediational processes
What is imitation
Others behaviour is observed, if behaviour is rewarded we are more likely to repeat the behaviour and vice versa (vicarious reinforcement/punishment)
What is modelling
Others act as blueprints for our behaviour. Role models can be real people or symbolic models.
identification is used as models with characteristics we relate to are more likely to be imitated.
Social learning theory : Research methods
Laboratory experiments on children, which allows strict control of variables and cause and effects
Bandura’s bobo doll experiment (1961)
72 3-5 year olds.
Groups watched adults interacting aggressively or non aggressively with a bobo doll. Aggression was more likely imitate if observed. Effect stronger if same gender, suggesting imitation and identification.
SLT strengths
- Bandura’s research used controlled variables and demonstrated behaviour was imitated, however lab experiment as real life examples of aggression is difficult to study
- Inclusion of internal mental processes is an improvement. Face validity
